FAPIER MACHINE AND METHOD OF MAKING PAPER.

Application filed. October 27, 1926.- Serial N0. 144,596.

My invention relates to paper machines and in particular to a slice fora paper machine and to a method of making paper.

It is my object to provide a slice, the free end of which will belocated adjacent the screen and beyond the breast roll center and beyondthe end of the apron so as to provide a space between the end of theapron and the end of the slice on the wire in which the stock canaccumulate, so that the water- .Figure 2 is a diagrammatic view ofthesingle slice construction;

Figure 3 is a diagrammatic view of a dual slice construction.

Referring to the drawings in detail, 1 is 'a stock box from which thestock makes its exit in the usual manner A support 2 is provided forsupporting, through the bracket 3, an apron 4, which is on the spindle5. Thus, the apron moves with the main frame and the breast roll 6 asthe parts are vibrated in the usual manner. A handle 7 is used to adjustthe position of the'apron on the wire 8.

A slice 9 is provided adjustably supported by the rod 10 whidli iscontrolled by a hand wheel 11. customarily, there are a number of suchrods and hand wheels adjusting the slice clear across the machine.

The stock enters a space, designated 12, beneath the slice 9 which ispivoted on the rod 18 supported in the frame of the machine. The stockpasses on to the apron 4 and thence on to the wire between the end ofthe apron and the end of the slice 13. It will be noted that this areaon which the stock first moves is to the right hand of the breastrollcenter 14 so that water can pass from the stock through this spacewhich is designated 15 before the stock passeson t0 the screen. In someinstances, it is desirable to usetwo slice boards. 7 In Figure 3 isillustrated one form of this apparatus. The slice designated 16 issuspended by the rods 17 of winch there may be any desired number in theusual manner .and is adjustably positioned thereto. A second slice ismounted on the rod 18, such slice being designated 19 and 1t iscontrolled by the rod or rods 20. It will be noted that the end of thissecond slice 19 is to the left hand side of the breast roll center,while the end of the slice 16 is to the "right hand, there being a spacebetween the apron 4 and the end of the slice 16 so that the stock can bedelivered on to the wire before passing under the slice 16.

The stock is delivered on .to the apron 4. and thence it is delivered onto the wire before it passes on to the second slice 16.

\Vith such 1 an arrangement, more water than is customary can be used inthe stock with resulting economy. This allows this excess water to drainoff quickly and the use of a greater quantity of water improves thequality of the paper. It is possible to run longer fibers when using agreater quantity of water. The amount of water released can be adjustedby adjusting the apron. By allowing the'water and stock to touch beforegoing under the slice, the stock has both sides caused to be alikebefore being spread in the final condition by the slice. Thispreliminary distribution is not effected by'the slice with theresultthat the paper coming from the machine is not subject to thecondition known as flowering, which is a group of mottled marks that hasa tendency to mar the paper on one side, the under side.

Bymy invention, I am enabled to eliminate this condition of floweringand to produce uniform paper with a similar appearance on both sides.

The best explanation that I know of for this condition of uniformity forthe paper on both sides is the release of .the water through the screenbefore the final spreading of the stock, and it is delivered thereforein final condition upon the screen. By allowing the stock to drain inits unspread condition before passing under the slice, I am enabled tocontrol this condition and produce uniform paper.

By using my apron in such'a combinatlon, which moves with the screen, Iam enabled to prevent streaks so that the entire combination givesuniform paper under all con ditions.

passing under the slice so that the stock water can drain through thewire before the stock passes under the slice, said slice beingpositioned at an acute angle with respect to the wire, whereby an areaof increased pres sure is formed between the slice wire and apron. r

2. In a pa er machine, a wire, a breast roll support or said wire and aslice having its end extending to such a point on the wire that thestock engages with the wire prior to passing under the slice so that thestock water can drain through the wire before the-stock passes under theslice,:and an apron resting on said wire so positioned that the stockflows on the apron before reaching the wire between the end of the apronand the end of the slice, said slice being positioned at an acute anglewith respect to the wire, whereby an area of increased pressure isformed between the slice wire and apron 3. In a paper machine, a wire, abreast roll support for said wire and a slice having its end extendingto such a point on the wire that the stock engages with the wire' priorto passing under the slice so that the stock water can drain through thewire before the stock passes under the slice, and anapron resting onsaid wire so positioned that the stock flows on the apron beforereaching the wirebetween the end of the apron and the end of the slice,said apron being arranged to vibrate with said wire, said slice beingpositioned at an acute angle with respect to the wire, whereb an area ofincreased pressure is formed etween the slice wire and apron.

i 4. In a paper machine, a wire, a breast roll support for said wire anda slice having its end extending to such a point on the wire that thestalk engages with the wire prior to passing under the slice so that thestock water can drain through the wire before the stock passes under theslice, and an apron resting on said wire so positioned that the stockflows on the apron before reaching the wire between the end of the apronand the end of the slice, said apron being arranged to vibrate with saidwire, and means to adjustably position said apron with respect to saidslice to adjust the area of the wire upon which the stock will first bedelivered before passing under the slice,

said slice being positioned at an acute angle with respect to the wire,whereby an area of increased pressure is formed between the slicewireand apron.

5. In a paper making machine, a wire, a breast roll, a slice on one sideof the breast roll and a slice on the other side of the breast roll,both of said slices being arranged at acute angles with respect to thedirection of movement of the wire, whereby areas of increased pressurewill be formed on either side of the breast roll center.

6. In a paper making machine, a wire, a breast roll, a slice on one sideof the breast roll and a slice on the other side of the breast roll, andan apron adapted to pass beneath the first slice and terminate on thewire before reaching the second slice, whereby the stock may drainthrough the wire before passing under the second slice, each of saidslices being positioned at an acute angle with respect to the apron andthe wire.

7. In a paper making machine, a wire, a a

breast roll therefor, an apron mounted on said wire having its free endbeyond the center of the breast roll in the direction of movement of thewire, and a slice positioned with its end over the wire and beyond theend of the apron whereby the stock will engage with the wire beforepassing under the slice beyond the end of the apron and can drainthrough the wire after it has passed over the top of the breast roll,said slice bemg positioned at an acute angle with respect to the wire.

8. In a paper making machine, a wire, a breast roll therefor, an apronmounted on said wire having its free end beyond the center of the breastroll in the direction of movement of the wire, and a slice positionedwith its end over the wire and beyond the end of the apron whereby thestock will engage with the wire before passing under the slice beyondthe end of the apron and can drain through the wire after it has passedover the top of the breast roll, said apron being adapted to move withsaid wire synchronously, said slice being positioned at an acute anglewith respect to the wire.

9. In a method of making paper, delivering stock on to a wire, allowingthe stock to partially drain through the wire and passing the stockunder the slice after having so partially drained and creating an areaof increased pressure between the end of the apron and the end of theslice to force the water in the stock through the wire at an increasedrate over the rate of its passing through the wire after it leaves theslice.

10. In a method of making paper, depositing stock upon an apron,delivering stock from the apron on to a wire to permit draining throughsaid wire, and passing the stock beneath the slice after a brief periodof draining and forcing the water from the stock at an increased ratebetween the end of the'apron and the end of the slice when it wire,allowing it to partially drain and move I will drain normally after itpasses, beneath said stock under a second slice and creating the slice.under each slice areas of increasedpressure 1 11.
